Live-Resin have made some improvements to the moulding quality and can now make the slot for ammo-clips in the lower receiver hollow. This will be introduced to all Live-Resin automatic weapons. Now ammo-clips fit very easily and positively. Scopes now also have a slot for easy fitting to RIS (Rail Interface System). You can even see the top cartridge in separate ammo-clips.
